This application is a divisional of my co-pending application Serial No.232,325 tiled Iune 19, 1951 and relates to improvements in mops of thekind comprising a sponge member that can be compressed between a pair ofplates or similar means for the purpose of removing the water and dirtabsorbed by the sponge during use.

The main object of this invention is to provide a mop the sponge ofwhich can easily be mounted and dismounted.

Another object of the invention is to provide a mop that can also beused under low furniture and does not damage it upon coming into contacttherewith.

The above-mentioned and other objects and features of the invention aswell as advantages thereof will be more readily understood from thefollowing description when taken in connection with the accompanyingdrawings, in which:

Fig. l is a plan view of the mop proper showing the arrangement of thesponge fastening devices,

Fig. 2 is a section on the line 2-2 of Fig. l,

Fig. 3 is a section on the line 3 3 of Fig. l, and

Fig. 4 is an exploded fragmentary perspective view of the securing meansfor the sponge.

Referring now to the drawing, which only illustrates a preferredembodiment of the invention, there is shown a cleaning sponge mounted ona support plate consisting of two portions 11a and 11b. To the plate 11ais secured a plate 21 carrying the socket 19 in which the handle 12lits. To the plate 11b is secured a plate 20 for connection to anysuitable means for swinging the said plate to a squeezing position onone or more hinges 13. Glued on top of the sponge and along the longsides thereof are two comparatively narrow rectangular strips 14consisting of a relatively soft but resistant material, e. g., woodfibre board. The strips extend beyond the outer edges of the supportplates, and while effectively stiiening up the sponge, do not damagewalls, furniture or other objects with which the mop may come intocontact when used. In the strips 14 there are pairs of spaced openings15 traversed by spaced arms of U-shaped lugs 16. These arms also passupwardly through overlying openings 15a in the support plates 11a and11b. The strips 14 are held to the support plates by cotters 17 insertedthrough holes in the arms of the lugs 16 and arranged so as to belongitudinally slidable. The central portion of each cotter ispreferably bent into a U-shaped loop, whereby the handling of thecotters is facilitated. By swinging the loops out of the depressions 18and sliding them toward the handle 12, they Will be retracted throughthe ears 16, thus permitting removal of the sponge head from the supportplates. As shown in Fig. 1, when the sponge has been attached to itsholder plate and the cotters have been slid through the holes in thearms of the lugs the loops are lowered into depressions 18 in the holderplate. Because of that construction it will be feasible to use theimplement under very low furniture.

I claim:

1. In a wringer mop, a rectangular sponge7 overlying hinged supportplates for the sponge and between which the sponge can be compressed,separate rectangular strips of soft stiif material between the spongeand the support plates glued to the top of the sponge and extendingalong each longitudinal upper side thereof and extending beyond theouter edges of the support plates, spaced openings in each strip, spacedopenings in each support plate, lugs having spaced arms provided withholes for receiving cotters, the arms of the lugs passing upwardlythrough the openings in each of the strips and the plates, a depressionin the plates and cotter pins resting in the depressions and slidable inthe holes of the arms of the lugs.

2. The wringer mop of claim 1, in which the cotter pins are partlyformed with U-shaped loops and are lowered into the depressions inlocking positions.
